VIRGEINIA,4 A. CORPORATION OF ROAD FORM Application filed. January 6,1932. Serial No. 585,106.

My invention relates more particularly to forms which are. used alongthe outer edges of concrete pavements to serve in the building of thepavements, as retainers for the concrete while the latter is setting,these forms in accordance with usual practice forming ways along whichthe concrete laying apparatus travels.

One phase of my invention relates toforms for the purpose above statedprovided as ways for the concrete laying apparatus and provided withflanges at their upper and lower edges having downwardly directed andupwardly directed lips, respectively, to strengthen the forms, it beingmy object in this connection to provide such a construction of form thatmay be formed by a rolling operation.

Another object is to provide a rolled form with the metal of greaterthickness at certain portions only thereof to afford -the desiredrigidity of the form at the minimum expense.

Another object is to provide a form which shall present the maximumstrength at the minimum cost of construction.

Another phase of my invention relates to the connecting together ofsections of the forms in end to end relation, it being my object in thisconnection to provide for connecting the sections together withoutrequiring the use of bolt-s, rivets, or other similar fastening means,in such a way that the sections will be held in properly alinedcond-ition and may be readily disconnected and re-connected at will, andpreferably to accomplish this with forms constructed of rolled shapes;and other objects as will be manifest from the following description.

Referring to the accompanying drawing:

Figure 1 is a view in side elevation, with certain intermediate portionscut away, of two form-sections embodying my invention, the sectionsbeing shown as connected together in accordance with my invention.

Figure 2 is a plan view of the structure of Fig. 1 showing the sectionsseparated but in alining position.

Figure 3 shows, by a perspective view, the mating ends of the adjacentform-sections.

Figure 4 is an enlarged sectional view taken at the line 4 on Fig. 1 andviewed in the direction of the arrow; and

Figure 5, an end view of a modification of the form.

Referring to the construction ofy road form shown in Figs. 1, 2, 3 and4, and which would be provided in form-sections of any suitable lengthto be alined in end to end relation alongside of the road to be built,two of such sections being shownV in these figures, each sectioncomprises a rolled base member 6 and arolled upright member 7, the basemember 6- being formed of a bottom plate portionA 8 having upwardlyextending flanges 9 and l0l along its opposite longitudinal edges andl aseparate angle bar 11 secured at its horizontal flange 12 to the uppersurface of the plate portion 8 at one end only of the form-section inany suitable way as by weldingv it thereto, with its vertical flange 13spaced from the flange 9 a distance substantially equal to the thicknessof the vertical upright platel portion of the member 7 described asfollows:

The member 7 comprises the upright plate portionv above referred to andrepresented at 14, this plate portion being provided at its upper endwith a substantially horizontal flange 15 exten-ding directly above theplate portion 8 and terminating at its' free edge in a depending lip 16.

The members 6 and 7 are slightly longitudinally offset in theillustrated assembled position of these members whereby the member 6 ofthe form-section extends at one end beyond the member 7 as shown of theconstruction at they right-hand side of Fig. 3 and the member 7 at theopposite end of the form-section beyond the member 6 as shown at theleft-hand side of Fig. 3, the members 6 and 7 being rigidly securedtogether in these relative positions in any suitable way, as for exampleby welding them in place, the lower edge of the upright portion 14 ttingflatwise against the inner face of the flangeV 9 as shown.

In the assembling of the form-sections in alining end to end relation,the projecting end of the upright portion 14 and represented at 14Z1 inFig. 8 is inserted into the channel represented at 8a and presentedbetween the flange 9 and the angle iron 12 of the adjacent form-sectionto abut at the end of the portion 14a against the inset end of theupright portion 14 of such adjacent form-section, the channelrepresented at 15a and presented between the upright portion 14 and thelip 16 containing a short channel bar 17 nested therewith and securedthereto in any desirable way and projecting beyond the end 14FL of theupright portion 14, the outer end of the channel 17 entering the similarchannel 15a of the adjacent form-section in assembling theseform-sections as stated, whereby the form-sections become so interfittedthat they function substanially as a unitary structure in resistingstresses directed laterally against them. Furthermore, by connecting theform-sections together .as stated they are admirably suited to resistthe stresses directed downwardly against them at the joints by thecement-laying apparatus in traveling over the flanges 15 wh1ch thus formtracks or ways.

The construction shown in Fig. 5 constitutes an embodiment of theinvention where the interfitting of the form-sections together as statedis not provided for. ln this construction which, in a sense, is asimplification of the form shown in the preceding figures, the formcomprises base and upright members 18 and 19, respectively, of the samegeneral form as the members 6 and 7 the member 18 having the base plateportion 20 with the upwardly extending flanges 21 and 22 at itslongitudinal edges and the member 19 having the upright plate portion 23with the substantially horizontal flange 24 at its upper end providedwith the depending lip 25. This form of construction is thus ofsubstantially-L shape as in the case of the structure of the precedingfigures, the lower edge ofthe plate portion 23 fitting against the innerface of the flange 21 in which relative positions the members 18 and 19are rigidly secured together, as for example by welding them as shown.The angle bar 11 ofthe form of the preceding figures is omitted in thisconstruction as no provision is made therein for the connecting togetherof adjacent form-sections as in the construction shown in Figs. l`4.

It will be understood from the foregoing that by constructing the formof a plurality of members such as the members 6 and 7 of Figs. 1 4, or18 and 19 of Fig. 5, a structure of such form, namely, that shown, as toprohibit-the production thereof as an integral Structure by a rollingoperation, may nevertheless be produced by such an operation; it beingunderstood that it would not be possible to roll the forms of eitherFigs. 1`4 or 5, as one-piece structures because of the ange 10 and thelip 16 of the one construction, and

5 the flange 22 and the lip 25 of the other construction. By makingthese forms in separate parts as described and connecting them togetherto produce the desired shape or form, these several parts may beprovided as rolled shapes.

Certain of the advantages of making the forms of rolled shapes, inaddition to those advantages manifest from the foregoing description,are that such forms, are stronger than those made of plates bent toshape, and may e rolled with the metal thickened at those portions,subjected to the greater stress, as for example at the flanges 10 and 22and at the junctures of the upper iianges of the upright member with theupwardly extending plate portions thereof as shown, while economizing inthe use of metal at the portions thereof subjected to the less intensestresses.

lVhile l have illustrated and described certain forms in which myinvention may be embodied l do not wish to be understood as intending tolimit it thereto as the invention may be embodied in other forms andthose shown modified and altered without departing from the spirit of myinvention.
